Lower control arm bolt snapped .. while the car was parked

While stopped for gas in Maine this week (on vacation), I heard a pop/snap. Looked under the car I noticed a bolt head snapped off. I didn't immediately spot the problem until I went over a bump and braked. I looked under the car while the front weeks were turned and noticed the lower control arm, separated from the frame. 7.5 hours of labor, and $10.50 in parts, I'm back on my way. Thanks to Oregans Halifax, and Breton Toyota Sydney, for not looking out for me. This could have been clearly avoided if the service people were a little pro active, and simply replaced the two bolts before they snapped off. The car has 97,000 km and has always been dealer serviced ( including a recent MVI ) Shame on Toyota for using sub standard parts. Clearly a recall should be in the works.

Pro active on replacing bolts that are not wear items in any sense and should have never failed like this to begin with?

I do agree with weak bolts though, there's a couple engine bay bolts that I've loosened that snapped which should not have under the pressure that they did. A suspension bolt should be at least a Grade 8 bolt and normally doesnt' break unless other conditions are present (like it's loose for some reason).

There is a TSB for those bolts corroding and snapping.

Because a TSB is not a recall. It is an informational document that saves technicians troubleshooting time on known issues.

So it's a lot more than a bad bolt if a whole component need be replaced.
OR that bolt was under-torqued and the resultant free-play would damage the other pricey part.
Thankfully my out of warranty 2008 sedan has exibited no such pricey clunk.

WOW they recommend a new cross member along with new CA's and a particular bolt. Damm.

Sounds like the bad bolts wear a hole into the CM as they break or something along those lines. Interesting.

At this rate you guys might as well get those bolts swapped out before they break so you don't have to go through the extra expense, shouldn't take more than 20 minutes on a hoist.

Perhaps I spoke too soon!
Clunking started Wed. afternoon. I'll run it up the ramps tomorrow and investigate. Sounds like the symptoms in the TSB. Clunk when braking, then clunk with re-accellerating and clunk over bumps.
Of course my warranty is done and it doesn't look like a driveway job.
Cha-ching!!! This may be our first trip to the service department. :(

Update: Sure enough, the head of the drivers side control arm rear bolt is gone. It broke off at the head so the stud is still intact so the arm cannot become dislodged.
I'll investigate other more reasonable solutions on Monday as the TSB is a very pricey process.

Update:
Visited Burlington Toyota/Scion this afternoon.
In Canada the TSB includes only the new, improved bolts. No new cross-member or control arms are specified. Approx. 3.5 hours (at $98.00 per hour) labour plus an alignment at ~$99.00. The bolts are ~$8.50 each.

Tomorrow an independant shop will investigate whether they can remove the broken bolt without dis-assembling the front end. Welding a large nut to the bolt shaft may be an option. A much cheaper one.

I was gonna say that welding another nut/etc onto the existing piece should do the trick if there's enough material protruding past the subframe.

Keep my fingers cross for ya!

Thanks to Corporate Autoworks in Burlington!
Today they easily removed the broken lower control arm bolt using an air chisel to turn it out far enough to grab it with vice grips. Then they cut a screwdriver slot in the end, put on some never-seize and re-installed it so I can nurse it around town for another day.
Two updated bolts will be delivered tomorrow by Burl. Toyota for installation at Corporate Auto.
I'm looking at approximately one hour of labour, two bolts at $8.50 each and no need for another $100.00 alignment.

Update: Today's final total incl. removal of the old and installation of the new updated parts = $135.00

Advice to all... order the bolts and replace yours now. You can do it yourself for about $20.00 before they break.

Glad yours wasn't pricey.

I also agree with the last line 100%, it's an EASY job and will save you $$$$$ down the road.
